Help with File reading and writing

[baltimore]

Hi, I am having problem and just need some coding lines that reads a file into an array so it can be edited in the array and than rewrites it to the file later on.

Also another question, is there a way to add more to an array with out creating a new one and so forth?

Thanks.

I would use a linked list (java.util.LinkedList) to put the lines in.

LinkedList lineList = new LinkedList();
BufferedReader br = new BufferedReader(new FileReader("FileName"));
String line;
while ((line = br.readLine()) != null)
{
lineList.add(line);
}
br.close();

On output I would use a PrintWriter and an Iterator over the LinkedList.
